Thermal expansion seamless steel pipe knowledge collection--51 steel pipe network to provide hot-expanded seamless steel pipe is what we often say the thermal expansion pipe, the density is relatively low but a very strong contraction of the steel pipe, (seamless steel pipe) can be referred to as thermal expansion pipe . A paddle finish rolling process in which the diameter of the pipe is enlarged by a cross-rolling or drawing method. The thickening of steel pipes in a short period of time can produce non-standard and special models of seamless pipes with low cost and high production efficiency. It is the current trend in the field of international pipe rolling.
China's current thermal expansion tube production standards:
Thermal expansion seamless steel tube: GB3087-1999
Hot expanded seam steel pipe (seamless steel pipe): GB/T3091-2000.
